I'm using the RCF Art 310A for stage monitoring, and it is fine at lower volumes. If cranked to loud, loud volumes, it suffers a little.
For my uses, it's exactly what I need: light, transportable, relatively accurate, powered, smooth, not harsh or brittle.
I wouldn't recommend it for your only amplification, except in small garage or coffee house type settings; much larger, and you may need to crank it into the range where it doesn't project quite so well.
I got mine used, with a cover, for less than $400, so it fits the bill well, within these parameters.
